JOSEPH BIJ UR, OF NEW YORK. N. Y., ASSIGN OR TO THE GENER BATTERY COMPANY, A CORPORATION OF NEW YORK. STORAGE BATTER Y.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To all whom it may concern.-

Be it known that I, Josnrn BIJUR, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Storage Batteries, of which the following is a specification, accompanied by drawings.

This invention relates to improvements in storage batteries, more particularly to the strapfor connecting the plates together.

The invention has for its object to insure a firmer connection than heretofore between the plates and the strap to facilitate the operation of connecting the plate-lugs to their connecting-strap.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of means for carrying out the invention, embodying the features of construction, combinations of elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which Figure 1 is a side elevation, partly broken away, of a strap connected to a number of negative plates. Fig. 2 is a plan view of the same,partly broken away. F ig. 3 is a trans verse sectional view of Fig. l, partly broken away. Fig. 4 is a transverse sectional view of a strap and a plate embodying a modification of the invention.

Referring to the drawings, A represents negative storage-battery plates having the lugs B, and O represents the connecting-straps for the plates having the terminal lugs or ears D.

The strap C has formed integral therewith the downwardly and depending projections or lugs E, and the lugs B and projections E, as shown, have beveled ends F and G, by means of which the lugs B on the plates are burned onto the projections E on the strap. In order to carry out the operation of burning, the plate is laid on its side, so that the meeting beveled surfaces F and G of the projection E and lug B form a pocket, which is filled with lead, suitable clamps being arranged each side of the lugs to form said pocket for the lead.

The plate A may be a hard alloy, while the strap B is all lead or soft alloy. The projections or lugs E on the strap are preferably of the same metal as the strap. Preferably the projections E on the strap are provided with fillets H for strengthening purposes.

There are a reat many advantages in this construction of strap. Heretofore one of the common ways to connect the lugs or batteryplates to the conducting-strap was to provide holes in the body portion of the strap, thrust the lugs on the plates through said holes, and then burn the lugs to the strap. This construction, however, makes a weak joint between the plate and the strap, because the metal of the plate extends up to the strap, the joint cannot. be seen, and it is difficult or impossible to make fillets at the 'oint for strengthening purposes. It has found that the plates are apt to break away from the straps at this point just below the strap, for this is the point at which maximum vibration occurs and at which provision should be made for great strength.

According to the present invention the lugs D are cast inte 2.1 with the strap and are provided with fil ets H, so that the point of maximum vibration in the connection between the stra and the plate is made as strong as possib e and can readily be made of softer metal than the plate itself. The joint between the lugs B and E occurs farther down nearer the plate, where there is less vibration and where the joint can be readily made, and this joint, moreover, is open to inspection.

Any plate may be removed and replaced with ease, for it is only necessary to separate one 'oint in order to replace a plate.

The invention may also be applied to connecting batterylates A, as in Fig. 4, to bus-bar J. In tiis modification of the invention the bus-bar is provided with horizontallyrojectin lugs K, havin beveled surfaces while t e lug O of the p ate is arranged horizontally and provided with a beveled surface P. The space between the beveled surfaces P and L on the lugs O and K is then filled with lead to burn the plate to the bus-bar.

Obviously some features of this invention may be used without others, and the invention may be embodied in widely varying forms;

Therefore, without limiting the invention to the devices shown and described and AL STORAGE.

een

without enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:

1. The combination with a connectingstrap having projections in the plane of the plate to be attached thereto, and batteryplates burned onto the said projections.

2. A connecting-strap for battery-plates having projections in the plane of the plates to be attached thereto.

I 3. A connecting-strap for battery-plates having projections in the plane of the plates to be attached thereto, said projections having beveled ends.

4. The combination of a connecting-strap having projections in the plane of the plates to be attached thereto, battery-plates havin lugis, said projections and lugs having beveled en s.

5. An element for a storage battery con- 1 sisting of a strap having dependent lugs of the same metal as the strap and plates joined to said lugs, the joints between the plates and the lugs being in the length of the lugs in contradistinction to being arranged at the points at which the lugs join the straps.

6. An element for a storage batte consisting of a strap having dependent ugs of the same metal as the strap, plates joined to said lugs, the joints between the plates and lugs being in the length of the lugs instead of at the ends of the lugs.

In testimony whereof I have signed this specification in the presence oftWo subscribing Witnesses.

JOSEPH BIJUR.
